Their fourseam fastball generates a very high amount of groundballs compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action and has slightly above average velo. Their slider generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. Their curve results in more flyballs compared to other pitchers' curves and has little depth. Their sinker has surprisingly little armside run, results in somewhat more flyballs compared to other pitchers' sinkers, has slightly above average velo and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 3 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their cutter (take this with a grain of salt because they've only thrown 3 of them in 2026) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has little cutting action, has slightly above average velo and has some natural sink.
